Victims of Twilight

I've researched, and I've written
about when, "twilight time" appears,

history proves it's different each night
and there's something about shadows, and mirrors.

But, I can tell you something
that narrows it down, even more,

just grab an odd numbered moonbeam,
and, you'll be gone before your feet hit the floor!

That's not to say it happens, everytime,
it depends greatly, on ebb and on flow;

but, catch that light splinter, at just the right moment,
and, when it happens...believe me, you'll know!

There's no other way to describe it,
than that, it involves a great deal of luck;

but, make sure you bring along your shadow, or else...
..in that world, you'll inevitably be stuck!
